Hello kids, today we'll learn about the carbon cycle. It is one of the most important cycles on earth. how it works is carbon flows between each reservoir in an exchange called the carbon cycle.
Well, let me just show you!
Sir Humphry Davy
In today's adventure, Sir Humphry finds himself exploring the sole process that drives the earth and keeps things in balance. That process is.......The Cabon Cycle.
Narration: "Okay kids, before we start here's some keywords to understand. Input, reservoirs, flow, and photosynthesis. Every cycle has an input, the input is what drives cycles. In our case, the sun is the only input in the carbon cycle. "
Narration: We covered that our input was the sun, but what happens then. The sun doesn't provide the carbon but the light needed for plants to do photosynthesis. Photosynthesis is when green plants take CO2 water, and sunlight to make food. After is the plants can make their food and keep repeating the process. Each time they perform the process, they take CO2 out of the atmosphere
Narration: Now that the plants had their food, its the animals turn. The animals eat the plants or other plants and store the CO2. This is called Ingestion, the process of taking food into the body.
Narration: After Ingestion, CO2 makes its way back into the atmosphere. After animals and plants die, in the process of decomposition the CO2 gets respired by the decomposers.
Narration: But CO2 is also found in the ground as fossil fuels like oils and coal. The reason for that is due to fossilization of dead animals or things like poop. Fossilization is when pressure, heat, and time preserve something over time under layers in the earth.
